For continuous-flow or intermittent gas lift in tubing or annular flow applications:
Variable Load Valves
Made in the USA
These wireline-retrievable, differential gas lift valves are primarily controlled by injection gas pressure. The valves are installed in a side-pocket mandrel and used to control injection gas pressure and its flow from either the annulus or tubing, based on the porting of the 1” (25.4 mm) mandrel. The variable-load valve operates on the difference in pressures between the casing and tubing. A typical installation relies on a greater casing rather than tubing pressure to close the valve.
• Replaceable floating seat
• Integral reverse flow-check valve with resilient and metal-to-metal seals
• Pressure rating up to 5,000 psi
• No bellows or nitrogen charge (therefore not temperature sensitive)
• Stainless steel or premium materials available
• Temperature rating of 275° F (135°C) (standard service)
